If you've got the perfect song for the perfect moment and you want other people to know about it, Snippit makes it happen. Imagine another version of Twitter in which every tweet is an audio sample for you to listen to.

Song clips can be between 4 and 10 seconds long, and if you don't have any digital music, the app connects with iTunes to download free 30-second samples. Check out the video below for more, or click here to take a screenshot tour of the app. Snippit is available for free in the App Store right here.

The first time you start the app, instructions will walk you through how to use it.

You can use music that's already on your phone or grab a free 30-second song preview from iTunes.

I don't have any music on my phone, so let's visit iTunes to get a sample.
